3 body regions of insects - head, thorax, abdomen 4 Main Routes of Bodily Entry - Skin Eyes Mouth Lungs 4 types of insect mouthparts - -chewing -sponging -siphoning -piercing/sucking Advantage of Fumigants - toxic to wide range of pests - complete penetration Advantages of Aerosols - ready to use, easy to store Advantages of dust - easily handled with low equipment cost Advantages of Emulsifiable Concentrate - 1. Easy to handle, transport, and store. 2. Easy to pour and measure. 3. Little agitation required. 4. Not abrasive. 5. Won't plug screens or nozzles. 6. Little residue on treated surfaces. Advantages of granular - easy to apply, low drift hazardAdvantages of microencapsulated - AI slowly released over long time - longer treatment Advantages of soluble powders - low cost and low phytotoxicity Advantages of Wettable Powders - low cost, low phytotoxicity Aerosols - AI in solution packaged in pressurized container antidotes for organophosphates and carbamates - atropine sulfate and protopam chloride (2- PAM) Applied Controls - Pest control measures used by humans. These include biological, cultural, mechanical, and chemical control. arachnids - A member of a major arthropod group that includes spiders, scorpions, ticks, and mites. All members have eight pairs of walking legs. 2 body segments: cephalothorax and abdomen centrifugal pumps - -longer lasting -expensive -high volume capacity (125 gal.) -low pressure (50 psi) complete metamorphosis - egg, larva, pupa, adult ex: beetles, ants, wasps, bees, moths, butterfliesCritical Pesticide Control Area - Critical Pesticide Control Area - may be designated if the unrestricted use of pesticides on a candidate area is likely to cause significant effects to: -endangered species -significant invertebrate species or habitats -quality of surface or groundwater supplies -health of sensitive individuals -government managed natural resources Crustaceans - head, thorax, and abdomen mandibles, 2 pairs of antennae, 5+ leg pairs DDT - developed during WWII to combat typhus outbreaks and other insect transmitted disease Disadvantage of Fumigants - high hazards - a lot of precaution Disadvantages of a dust - risk of drift and inhalation Disadvantages of aerosols - inhalation and drift risk Disadvantages of Emulsifiable Concentrates - high AI concentration (greater than 80%) means low margin for error easily absorbed through skin typically high phytotoxicity Disadvantages of granular - does not stick to foliage, hazard to non-target species, especially birds Disadvantages of microencapsulated - nearly insoluble and require constant agitation Disadvantages of soluble powders - inhalation riskDisadvantages of Wettable Powders - needs a lot of agitation inhalation risk *abrasive to sprayers* Dust - low concentration of AI (0.5-10%) in finely ground inert substance - used dry Earliest recorded use of chemical pest control - sulfur burned to control mites in 2500 b.c. Emulsifiable Concentrate (EC) - A pesticide formulation produced by mixing an active ingredient and an emulsifying agent in a suitable petroleum solvent.
